TFS High Port Heads

The Street Heat Aluminum Small Block Cylinder Head is the most well known High Performance head because of its strength and versatility. FOX LAKE offers Five STAGES of CNC PORTING to cover 289 up to 450 cubic inch engines.

STAGE 1: Supercharger Porting Package

This Package is best suited for the 289-357 cubic inches range with a port matched intake manifold, upgraded fuel system and free flowing exhaust system. A mild cam or 1.72 ratio rocker arms will add more horsepower. Although this package works exceptionally well on naturally aspirated engines, it was designed for maximum power with a supercharger system running between 6 to 12 pounds of boost pressure.

STAGE 2: Competition CNC Porting

Stage 2 Competition Porting is designed for 289-357 cubic inch engines in the 3000-7000 RPM range depending on the application, Street or Strip. EFI Cars should have our Stage 2 Trick Flow Track Heat or a Stage 2 ported Edelbrock Performer RPM 2 for a good flowing head/intake combination, CARBURETOR Cars should use a port matched Edelbrock Victor Junior Intake for best results.
